To all whom it really concern:

Be it known that I, JOSEPHINE G. Coon- KANE, a citizen of the UnitedStates, residing at Chicago, in the county of Cook and State ofIllinois, have invented certain new and useful Improvements inDish-Washing'Machines, of which the following is a full, clear, andexact description.

My invention relates more particularly to hand operated dish washingmachines and it has forits primary object to provide an improved, simpleand efficient form of hand operated dish washing machine.

Another object of this invention is to provide an improve form of nozzlefor searching every part of the interior or casing of the machine with athin sheet ofwater. 1 Another object of the invention is to provideimproved and simple means for holding cups, glasses and ther like obects in an .3111- cleansing stream.

With these ends in view, the invention consists in certain features ofnovelty in construction, combination and arrangement parts which willnow be described with reference to the accompanying drawings and morearticularly pointed out in the cla1ms.

In t 'e said drawings: Figure 1 is a perspective view of a dish washingmachine embod ing this invention, with the casing partial y broken away.Fig. 2 is an enlarged side'elevation, partly in vertical section, of thenozzle and its operating handle. Fig. 3 1s a transverse section thereofon the line 3-53, Fig. 2. Fig. 4 is a detail section on the l ne 4-4,Fig. 2. Fig. 5 is a detail view of the joint between the nozzle and thestand pipe; and Fig. 6 is a vertical transverse section 0 the cup rack.

1 is a casing of any suitable form and construction provided with ahinged 11d 2 and having at one end a pump chamber 3 in which is situateda force pum 4 of any ap propriate form, which is capab e of beingoperated by a handle or lever 5 for forcing waf the chamber 3 and into astan ter out o suitable connection of pipe 6 through any pipes 7, thestand pipe 6 being situated ref;

' a on erably at one side of the casing 1 and at the mid length thereof,as better shown in Fig. 1, so as to be in an advantageous position fordirecting the s ray or sheet of water therefrom against the ishes orother articles at all points within the casing. On the u k d of" thestand pipe 6 1s rotatab y I ject through an aperture in the edge 0mounted a nozzle, which is of special and peculiar form for producing asheet of water of the desired form and direction of flow from theminimum volume of water and the minimum force exerted thereon by thepump 4. In order that this nozzle may be readily rotated by one hand ofthe operator while the other hand manipulates the pump lever 5, thenozzle is provided with a laterallyprojecting handle 8 mounted upontheupper end of a short section of tube or pi e 9, which is closed atits upper end and is a apted to ript e lid 2 when the lid is closed, theaperture being open at one side so as to permit the lid to be 0 ened andclosed independently of the hand e 8. The lower end of the tube 9isprovided with any suitable swivel connection with the stand pipe 6. Inthis exemplification of the invention, the upper end of the stand pipehas secured to it a collar 1 1, which constitutes a socket for receivingthe lower end of the tube 9 and which is provided with an L-shaped slot12 for the introduction and engagement of a locking lug or pin 13projecting from the side of the tube 9 so that when the tube is insertedin this socket 11, it will be capable of rotation throughout the degreepermitted by the horizontal portion of the L-slot, the lug 13 in themeanwhile holding the tube 9 from being forced out of its socket b thepressure of the water.

The disc arge portion or member of the nozzle is so formed, constructedand arranged as to reduce the volume of water forced upwardly throughthe stand pipe 6 to a fan shaped sheet, as contradistinguished fromspray, and which occupies a vertical plane while being capable ofrotation on a vertical axis through the agency of the nozzle 8 forsearching every point within the casing 1 throughout its entire widthand length and from top to bottom, so that all of the articles supportedat the side of the casing opposed to that on which the nozzle issituated, as well as all of those articles which are located u on thebottom of the casing, will receive the full force of such sheet. Inorder to produce a sheet of water of this form, the discharge member ofthe nozzle is constituted by a horizontal projecting protuberance whoseu per side 14 is closed from end to end, whi e its lower side 15 iscurved from a point level with the upper side downwardly to a point inconjunction with the lower edge of an opening 16 in the side of the tube9,

V or substantially vertically,

stream and slightly inclined through which the water discharges into thesaid protuberance, and this lower curved edge of the protuberance isprovided with a slot 17 from end to'end. It will thus be seen that adischarge member is constituted, capable of casting a fan shaped sheet,with its edges extending horizontall and vertically, so that while allthe water will be thrown with great force against the sides and thebottom of the dish chamber, none of it willbe thrown orsplashed out ofthe chamber.

' The cup holding rack shown in detail in Flg. 6 consists of twosupports 18 19 at each end of the casing 1 and a number of horizontalbars 20, 21, 22, 23 which connect these two pairs of supports togetherand which serve to support the cups in such a position that their opensides will be directed downwardly, as indicated in dotted lines in Fig.6, so that particles dislodged by the spray will be washed andeventually carried to the bottom of the pump chamber 3, whence the sudsand all objectionable matter may be removed through a connection 24. Itwill be seen that all four of the rods 20, 21, 22, 23, are required forsupporting a cup, and it will be understood that this set of rods may beduplicated as often as the height of the supports 18, :19 will permitThe two rods 23, 22 and the two rods 20, 21, respectively, lie in planeswhich converge downwardly, the rods 20, 21 being respectively slightlylower than the rods 23, 22, and which rods 20, 21 are farther apart thanthe rods 22, 23, whereby thelatter rodswill serve to sustain the bottomand side of the cup while the rod 20 will be engaged by the top ofthecup, the rod 21 serving to limit the downward movement of the cup in theevent it should be small enough to descend an objectionable extentbetween the rods 20, 22. In order that the device maybe adjustable foraccommodating cups and glasses of various sizes, the supports 18, 19areadjustable with relation to each other onanumber of dowels or pins 25passing therethrough, as shown in Fig. 6, whereby the standardsmay bewedged apart or driven together as may be required. By this arrangementof the horizontal bars 20, 21, 22, 23, it will also be seen that whilethe cups or glasses in the upper tier may be presented toward thehorizontal portion of the as described, the cups or articles of thelower tiers may be presented in a more or less downward direction so asto receive the full force of that portion of the stream which isdirected toward them direction, thus enthe tiers to receive abling thecups in all of stream in their inthejdirct force of the teriors. Havingthus described 111 invention, what I claim as new therein and desire tosecure by Letters Patent is:
